About Masters Running & Age Grading
Key facts for masters runners using age grading to track performance.
What WMA factors represent: The age factor encodes how much slower a world-class master runner is expected to perform at a given age compared to their peak (around age 28–32). A factor of 0.85 at age 55 means the world-class 55-year-old runs about 85% as fast as the open world record.
Tracking improvement: Many masters runners maintain or improve their AG% year-over-year even as raw times slow slightly. Rising AG% means you are aging better than the world-class decline curve — a meaningful training metric.
Road vs. track: This calculator uses WMA 2023 road factors. Track events (800m, mile, 3K, 5K) use separate tables with slightly different values. Road factors are used by the vast majority of age-graded race results.
WMA Age Factor Curve
How the age factor changes from age 20 to 90 for your selected distance and sex. The gold dot marks your current age. A steeper curve means faster performance decline for that distance.
Switch distance or sex in the Calculator tab to update this chart. Longer distances (marathon) show a steeper decline curve than shorter distances (5K).
